Snipe-IT: Stored XSS via Custom Field name in asset-list column headers
OSV carries this publisher advisory for snipe/snipe-it. This is an aggregated source copy; consult the original publisher and compare update dates.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

snipe/snipe-it
source listedECOSYSTEM: introduced 0; fixed 8.7.0
### Impact A user with the "customfields.create" permission can store HTML/JS in a Custom Field name, which is later rendered as an asset-list column title WITHOUT escaping at app/Presenters/AssetPresenter.php line 364 ('title' => $field->name) and injected into the table header by the bundled bootstrap-table plugin. It executes for anyone who opens an asset list (e.g. /hardware), including superusers, on page load with no interaction. Since "customfields.create" can be granted to non-superusers, a lower-privileged user gets script execution in a superuser's session -> privilege escalation. STEPS TO REPRODUCE 1. As a user with "customfields.create", create a Custom Field named: `` 2. Add the field to a fieldset that is associated with an asset model. 3. Open `/hardware` -> the payload executes on load. DEMONSTRATED IMPACT An account holding ONLY "customfields.create" (HTTP 403 on /users) planted a payload that, when a superuser opened /hardware, issued an authenticated request in that session and granted the attacker's own account the "superuser" permission (afterwards: GET /users = 200, isSuperUser() = true). ROOT CAUSE - Blade {{ }} encodes the data

What to do next
- vendor patch
The original advisory lists fixed boundaries 8.7.0 for snipe/snipe-it. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
